Rear final drive bearing replacement
 

I came across this wonderful video of how to replace the BMW final drive bearings and replace with new bearing and shims.

The guy is a bit pedantic but he can screw around with the love of my life any time.
Ignore the horse at the beginning and other "faults" along the way.

Ace mechanic - less excellent video producer. However it really is packed with information to save hours of time and tons of money at BMW dealers.
